To all whom it may concern.'

Be it known that I, CHARLES W. MANZEL, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and'useful Tinprovement in Lubricating Apparatus, ofwhich the following is a specification.

This invention relates to a force-feed lubricating apparatus designedmore particularly for the steam-cylinders of locomotives; but the sameis also applicable to other engines in which it is desirable to supplyoil to different points from a common source.

The object of my invention is to provide a simple apparatus of this kindwhichinsures a uniform distribution of the oil to a plurality ofchest-plugs or similar lubricating devices connected with the same feedpipe or conduit.

In the accompanying drawings, consisting of three sheets, Figure l is aside elevation of the apparatus applied to a locomotive which is-sliownby dotted iines. Fig. 2 is an enlarged vertical section of thelubricator. Fig. 8 is a longitudinal section of the distributer. Fig. 4is a horizontal section of one of the chest-plugs in line 4 4, Fig. 5.Fig. 5 is an enlarged vertical section of the same.

Similar letters of reference indicate corresponding parts throughout theseveral views.

A indicates a force-feed lubricator of any suitable construction, whichis located in the cab when the apparatus is applied to a locomotive.

In the lubricator shown in the drawings,

Fig. 2, B is the oil-reservoir, C the cylinder of the force-pump locatedin the lower ortion of the reservoir, and C the pump-p unger, which maybe reciprocated by any suitable or well-known actuating mechanism.

d dare check-valves located in the discharge-passage of thepump-cylinder, and E is the delivery-passage of the lubricator,connected with said discharge-passage and preferably containing asuitable stop-cock or con- Y trolling-valve F.

G indicates the chest-plugs of one of the steam-cylinders, thelocomotive (shown by dotted lines in'Fig. 1 being of the superheatedtype in which each cylinder is provided with three of such plugs. hindicates the individual feed-pipes of these plugs, which arerespectively' connected withthree discharge branches or nipples h of amanifold or distributer H, las shown in Figs. l and 3. The distributeralso has an inlet branch or nipple screw-threaded collar or union g3.

h2, which is connected with the delivery-pas-A sage E of the lubricator,so that the several chest-plugs connected with the distributer aresupplied by the same pump. Each of these chest-plugs is provided with achoke or constrictedpassage for effecting an equal disy tribution of theoil to the several plugs supplied by the same pump, and for this purposeing the post and provided in its lower-end with a tapering socket g2,which receives the correspondingly-shaped upper end of the post. Thepost and the head are united by a The head has an axial oil-passage g4,provided at its lower end with a seat g5, against which a\ check-valveg6 is adapted to close. This valve has a grooved or winged stein 97,which eX- tends upwardly through an enlargement gf* of the oil-passageg, and the same is held against its seat by a spring i, applied to saidstem and bearing at its lower end against the bottom of said enlargementand at its upper end against a nut or collar i', secured to the stem..The valve g prevents the water of condensation from entering thefeed-pipe 71, and also prevents loss or waste of the oil in the feedpipewhen the locomotive is drifting or` at rest.

j indicates a choke-plug applied to the upper end of the head g andprovided with a constricted central passage j', which is graduallycontracted from the upper end to about the middle of the plug and thenflared toward the lower end thereof, as shown in Fig. 5.

c indicates a hood or inlet-chamber surmounting the head g and inclosingthe chokeplug This chamber is provided at 'its uper end with an inletbranch lc', to which the fiont end of the feed-pipe h is connected, andat one side thereof with a vent or vent-nipple l for the escape of theair in said feed-pipe and the chest-plug. The outer portion of the boreof this vent-nip le is enlarged to form an internal seat or shoulder Z,a ainst which the inner end of a screw-plug m iears, which normallycloses the outer end of the reduced portion of said bore. duced at itsinner 'end to leave an annular s ace m between the saine and the wall ofthe nipple andis provided with a longitudinal passage m2, which extendsfrom its outer end nearly to its inner end and communicates This plug isre- IOO IIO

several chest-plugs connected therewith Iis checked or retarded in its'passage through the plugs by thek constrictions in the choke- Thesurplus or portion of the' oil in each chest-plug which does not find aquick exit through the restricted passage of its chokelug 'y` exerts aback ressure upon the oil in t e distributer H an the feed-pipes hof theother chest-plugs which equalizes the pressure in all of the chest-plugsof the same eed-pipe, and thereby effects a uniform supply anddistribution of oil to them. To pro'- duce this effect, the actuatingmeans of the oil-pump should be of a character to impart quick andsudden impulses to the lunger, so as to drive the voil through the fee-pipes and into the chest-plugs with sufficient force and speed toproduce such equalizingor` back pressure. An suitable operatingmechanism which wifl produce that action of the plunger may be used forthis purpose; but I prefer to emplo an. air-motor of the type com risinga cy inder and piston and valve mec anisin for alternately admitting thepressure fluid to opposite ends of the cyllnder, the motor beingconveniently supplied from the usual pressure-tank ofthe air-brakeapparatus.4 l

As the lubricant is uniformly supplied to a y number of chest-plugs bythe same pump, the y necessity of-providing a separate pump for eachplug is obviated, thus simplifying the construction of the apparatus,rendering it more compact, and reducing' its cost accordwith thedelivery-passage of the pump, and a plurality of chest-plugsvoroil-posts connected with said distributer by individual feedpipes andveach chest-plug or oil-port provided with a feed-passage having a choke'or `constricted portion, anda check-valve arranged in said passage andclosing toward the corresponding feed-pipe, substantially as set forth.

In a lubricating apparatus, the combination of a reservoir, a umpsupplied therefrom, a manifold or distributer connected with thedelivery-passage of the pump, and a plurality of chest-plugs connectedwith said distributer andV each provided with a feedpassage, acheck-valve arranged in the feedpassage of each chest-plug, and achoke-plug arranged in each of saidA passages above the correspondingcheck-valve, substantially as set forth. f
